Got a question for you all. From what I have been noticing i have seen a lot of warlocks gemming for haste/mastery instead of Int at 520 ilvl and higher. Why is that, do those stats become better at higher ilvls or something? And if simcraft is saying so does it actually prove to be better while actually raiding in ToT and not just simming it.
I think at a certain gear level that Mastery/Haste becomes over twice as good as int, which is why a lot of them start gemming it because of the double secondary stats on gems. When this threshold is I can't remember at the top of my head, but I'm fairly certain that's the reason.
